A torso is the main part of your body that includes your chest and abdomen. It's essentially everything except your head and limbs.
When people talk about a torso, they often mean the middle section of something else - like a statue or a skeleton - where you'd see the body but not the head or legs. For example, imagine looking at an old Roman statue in a museum; the upper part is gone, but what's left is called the torso. This word can also refer to a life-size representation of the human body, often made for educational purposes like anatomy models.
The main part of the (human) body that extends from the neck to the groin, excluding the head and limbs.
